A bank's treasury department is responsible for managing the bank's money and ensuring the bank can access cash needed for daily business activity. The treasury department is also responsible for making sure that the bank is financially stable and able to assist its clients.
Working with the agencies responsible for regulating banks is another responsibility of a bank's treasury department. This can include getting updates on any changes to regulations regarding liquidity and the amount of capital that should be maintained. Treasury departments can also focus on any changes in the market, adjusting the bank's funds based on these changes.
